Here's a brief GamerZero interview with Sara Girard, Associate Brand Manager for D&D. Mostly, they discuss a philanthropic digital initiative to get kids into libraries. However, they also discuss exposing some folks to 4th edition at the D&D Experience convention in February. There's also a shot of the digital tabletop at about 1:17 that's just gorgeous. They're clearly putting a lot of work into making it an exceptional gaming tool, and not just your usual quick-and-dirty line-map thing.
